Query builder — Nested rule groups in Lantern's query builder

Lantern’s query builder, shown with a single rule and with nested groups.

A query starts as one plain rule, like user signups above a set number, with the Salesforce icon showing where that data comes from. Nesting only appears when you add an inner group, and rules can check for a change, such as active users has changed, as well as compare values. Every row keeps the same order, so even a long query reads line by line.
